Neptunium(IV) oxalate, Plutonium(III) oxalate

  • Source: "The Savannah River Plant recovers neptunium-237 by precipitation as neptunium(IV) oxalate. It is then calcined to neptunium oxide, mixed with powdered aluminum, and pressed into billets for fabrication into reactor targets. The targets are irradiated to produce plutonium-238 for use as heat sources in radioisotopic generators." and "Ascorbic acid was added to the neptunium feed before precipitation to reduce any neptunium(V) to neptunium(IV)." .
5x expanded by UnbihexiumFan (talk). Number of QPQs required: 0. Nominator has fewer than 5 past nominations.

  • I believe that one of the facts of the hook appears neither in the article nor in the cited source. This hook includes three facts: (1) neptunium(IV) oxalate is a compound used in nuclear power applications, (2) the production of neptunium(IV) oxalate involves ascorbic acid, and (3) ascorbic acid happens to be a nutrient, known as vitamin C in the context of nutrition. The first two facts do appear in the article and the source, but there's no hint of the third fact in the article, and more importantly, in the source. Technically the hook doesn't state the third fact either, but given that ascorbic acid is typically only called "vitamin C" in the context of nutrition, I feel like the hook clearly implies it, which is synthesis. This hook is very intriguing, so it'd be awesome if you can find a source that makes an explicit connection between neptunium(IV) oxalate and vitamin C. Without such a source, I think you'll need a different hook. Streded (talk) 20:44, 10 April 2026 (UTC)
    • In that case, it would probably have to be rephrased as to not imply that neptunium(IV) oxalate production involves vitamin C, since I can't find a source that explicitly states there's a connection between vitamin C nutritionally and ascorbic acid used in nuclear power. As for sourcing, https://doi.org/10.1016/j.advnut.2023.100155 states that ascorbic acid is one of two forms of vitamin C. UnbihexiumFan (talk | contribs) 21:46, 10 April 2026 (UTC)
  • ALT1: ...that the production of neptunium(IV) oxalate, a compound used in nuclear power applications, involves ascorbic acid (also found in nutrition as one of two forms of vitamin C)? UnbihexiumFan (talk | contribs) 21:46, 10 April 2026 (UTC)
  • I have also recently nominated Plutonium(III) oxalate for GA status, it is currently under review, and its production also uses ascorbic acid, so I have been considering doing a double hook in the case that the review passes. Would have to find sources, though. UnbihexiumFan (talk | contribs) 21:46, 10 April 2026 (UTC)
  • Plutonium(III) oxalate has passed the GA nomination! As stated, I am the nominator. To commemorate this, I propose a double hook:

  • ALT2a: ... that the production of plutonium(III) oxalate and neptunium(IV) oxalate, compounds used in nuclear power applications, involves ascorbic acid, also found in nutrition as one of two forms of vitamin C?
  • Full review needed of (now two) articles and the new ALT2a hook. (I have struck ALT2 because it contains a parenthetical, which is not allowed in DYK hooks; ALT2a has the same text but different punctuation.) Thanks. BlueMoonset (talk) 18:15, 3 May 2026 (UTC)
@UnbihexiumFan: Nice username! Both articles are new and long enough (598→6677 words and recent GA), within policy, and presentable. No QPQ needed as these are their first nominations. I'm going to propose wording changes that I want to check with you before I approve it. First, the chemical names are gobbledygook to non-chemists, so I'd like to soften them a bit. Second, it's common knowledge that ascorbic acid is a form of Vitamin C, and the explanation makes the hook overly wordy. What do you think of the following? Antony–22 (talk⁄contribs) 04:11, 7 May 2026 (UTC)
Thank you! yes, the new alt is fine.

@UnbihexiumFan: Okay, one more thing is needed: the article needs text with a reference saying that ascorbic acid is a form of Vitamin C. (Looking at Chemistry of ascorbic acid and Vitamin C#Chemistry it looks like only the L enantiomer is a form of Vitamin C and not the D enantiomer, though the cited sources are offline. The ascorbic acid used in the plutonium and neptunium reactions is likely racemic, but since that contains both enantiomers, the hook would still be true.) Antony–22 (talk⁄contribs)

@Antony-22: Where would I incorporate this into the article? I'm not sure how I would write that ascorbic acid is a form of Vitamin C. I could probably find a source; I read somewhere that ascorbic acid is a form of Vitamin C from a source about plutonium reduction. I appear to have lost the source, though.

If you do a web search for "ascorbic acid Vitamin C" you should find a bunch of sources, like this one. Maybe put in parentheses just a phrase that it's also known as a form of Vitamin C? Antony–22 (talk⁄contribs) 19:44, 12 May 2026 (UTC)
@Antony-22: So, something like ...ascorbic acid (C6H8O6; Vitamin C)[1]... in the text of both articles?
UnbihexiumFan (talk | contribs) 20:50, 12 May 2026 (UTC)
Maybe something more like "(also known as a form of Vitamin C)". There are other forms of Vitamin C so it needs to be specified. It's not really encyclopedic but it's needed for the hook, and if you want to remove it after the hook runs I wouldn't blame you. Antony–22 (talk⁄contribs) 04:55, 13 May 2026 (UTC)
Alright, I have added stuff to both articles. Is the hook ready for DYK now?

Good to go with ALT2b! Antony–22 (talk⁄contribs) 23:24, 13 May 2026 (UTC)
